IMPROVEMENT IN MACHINES FOR ASSORTING NAILS.

Specification forming part of Letters Patent No. 152,821, dated July 7,1874; application filed May 13, 1874.

To all whom it may concern:

Be it known that I, JOHN DJBAIRD, of Manchester, in the county ofChesterfield and in the State of Virginia, have invented certain new anduseful Improvements in AssortingAttachments for Nail, Spike, and TackMachines;

and do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, making a part of thisspecification.

My invention relates to devices for separating imperfect nails, spikes,or tacks, slivers, dirt, &c., from the perfect nails, spikes, or tacksin a nail, spike, or tack machine; and it has for its object toaccomplish this separation in a rapid and complete manner.

The nature of my invention consists in the combination, in a nail, tack,or spike machine, of one or more inclined stationary plates or rollerswith one or more inclined revolving rollers, as will be hereinafter morefully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a perspective view of my invention, and Fig. 2 is a planview of the same.

A represents the frame-work of a nail or tack machine. B B represent tworollers in cylindrical form, of metal or other suitable hard material,and of any required dimensions. These rollers are placed in an inclinedposition, as shown, and are made to revolve outward from the nailspassing between them,

which motion may be obtained from the spin dle of the nail-machine, orin any convenient manner. The roller 13 has its bearing at the lower endin a slotted box, 0, which is held to the frame by a setscrew, as, sothat the opening a between them may be made larger or smaller, asrequired, to suit different sizes of nails, or tacks, or spikes. Thisapparatus is provided with a wing, D, on each side, to conduct the nailsor tacks to the rollers.

This apparatus, properly put together, may be adjusted to the nail andtack machine under the point where the nail or tack leaves the dies. Thenails or tacks, as they are cut, fall on or are guided to the openingaby the wings I) l) on each side. The inclination and revolving motionof the rollers carry the good nails to the lower end of the apparatus,where they drop, through circumferential grooves b in the rollers, intoa keg or box, while the imperfect nails or tacks, slivers, dust, dirt,&c., fall through the opening a into a receptacle prepared for them.

The above simply refers to the employment of one pair of rollers,but itis self-evident that any number of rollers may be used, they beingarranged with openings between them; also, in place of pairs of rollers,each roller may be used in combination with a guideplate, with openingsbetween them, to be made adjustable in the same manner as abovedescribed.

I'ani aware that a slotted conductor, in combination with a nail cuttingand heading machine, is not new, the same being shown in the patentgranted to John Coyne, dated J nne 3, 1873; hence I do not claim suchcombination.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- The combination, in a nail,tack, or spike machine, of one or more inclined stationary plates orrollers, 13, with one or more inclined revolving rollers, B, as and forthe purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand.
